On March 21, Liu Zheng, the director of the Municipal Museum, led a group of seven staff members to Dawuyashicheng to conduct an investigation. Stone City is located in the Taibaijian Nanshan Dawu Cliff, Chaoyang Town, Lianyun District, Lianyungang City. The Dawuya Stone City site mainly includes three aspects: city walls, stone carvings and the foundation sites of buildings in the city. The city was announced as a cultural relics protection unit of Lianyungang City in 1993, and was named a cultural relics protection unit of Jiangsu Province in 2011.

　　Dawuya Rock City was built during the Xianfeng period of the Qing Dynasty and was funded by Zhang Jiantang, the grandfather of Zhang Baichuan, for the anti-twist army. There are only stone walls that are 1.2 to 3 meters high, 0.9 to 1.1 meters wide, and about 1,000 meters long from north to south. On the south side of the city, there is a huge rock inscribed with Zhang Baichuan’s "Story of the Wuya Stone City", which reflects that the local officials and gentry built the second city in order to resist Liu Tianfu’s Nian Army uprising. The construction was completed in the first month of the year (1862). According to the "Poems of Yuntai Tour Guide": "...dozens of houses were built in the city to avoid chaos in the village."

　　Dawuya Rock City is an important witness of Taiping Heavenly Kingdom’s activities in Lianyungang area, especially the stone carvings in the city, which are precious historical materials for studying the Taiping Heavenly Kingdom movement and the history of the Anti-Qing Dynasty.
